Sensory neurons transmit information towards the central nervous system. Which of the following is true concerning the movement of peripheral- information towards the central nervous system? A. Dendrites of the sensory neurons synapse with interneurons of the spinal cord. B. Axons of the sensory neurons synapse with motor neurons of the muscles involved in the spinal reflex. C. Axons of the motor neurons synapse with the interneurons of the spinal cord. D. Axons of the sensory neurons synapse with the interneurons of the spinal cord.

You identify a new neuron in the fruit fly's brain and find it contains acetylcholine. 1) Based on this identification, this neuron is (a) Excitatory, (b) Inhibitory, (c) Neither excitatory nor inhibitory, or (d) Either excitatory or inhibitory 2) Briefly explain your answer above. 3) How would you figure out your answer above? Briefly describe an experiment you would do. Edit Format Table

Which of the following is/are found only in the PNS? a. Nerves b. Astrocytes c. Myelin d. Lipofuscin e. Unmyelinated axons

for the Spinothalamic Tract, can you show me a diagram for the pathway from the peripheral structures of the body to the location inthe brain.a. Label the location of each neuron's dendrites, cell body, and axon terminal.b. Label the location (nervous system region) of the synapses involved in this ascending pathway.c. Label the location (nervous system region) of decussations, if any.

This is a biology question regarding nerve impulses. Neurofibromatosis type 1 is a condition where tumours can grow in the nerves near the skin. The growth of tumours prevents the action potentials from quickly travelling through the neurons. Identify the nerve structure from the image below and the division of the nervous system affected by neurofibromatosis type 1. CNS = Central Nervous System PNS = Peripheral Nervous System   Select one: a. Nerve Structure Division of Nervous System 3 PNS b. Nerve Structure Division of Nervous System 4 CNS c. Nerve Structure Division of Nervous System 5 PNS d. Nerve Structure Division of Nervous System 1 CNS

Multiple sclerosis is a demyelinating disease affecting the central nervous system. What type of cell would be the most likely target of this disease? Why? Which type of neuron, based on its shape, is best suited for relaying information directly from one neuron to another? Explain why. Sensory fibers, or pathways, are referred to as “afferent.” Motor fibers, or pathways, are referred to as “efferent.” What can you infer about the meaning of these two terms (afferent and efferent) in a structural or anatomical context?

Match the description with the statement that best describes the following regions                                                             synaptic knob                                                             axon hillock                                                             dendrites                                                             axon A. elongated projection that conducts electrical signals over long distances B. receives input from other neurons C. region of high denisty of voltage-gated channels, known as the trigger zone D. contains numerous vesicles containing neurotransmitter

You touch a hot stove and withdraw your hand before you perceive the pain. Identify the neural pathway involved in this response. a. stimulus --> motor neuron --> interneuron --> brain --> sensory neuron b. stimulas --> sensory neuron --> interneuron --> brain --> motor neuron c. effector --> sensory neuron  --> interneuron --> brain --> motor neuron --> stimulus d. effector  --> motor neuron --> interneuron --> sensory neuron --> stimulas e. stimulas --> sensory neuron --> interneuron --> motor neuron

Auditory information is processed initially by which lobe of the cerebral cortex?     a. temporal     b. occipital     c. parietal     d. frontal Which receptor type is regulated by both the presence of the ligand and the membrane potential of the cell on which the receptor resides?     a. D2-like dopamine receptors     b. 5-HT1 type serotonin receptors     c. Metabatropic (muscarinic) acetylcholine receptors     d. NMDA type glutamate receptors

Alzheimer’s disease is thought to cause a DECREASE in the amount of acetylcholine (ACH) being released into the synaptic cleft in specific parts of the brain. What would be a possible treatment for this disease?  (So basically- what would be a possible way to increase the amount of ACH in the synaptic cleft?)
